I've assumed that will about PKG_CONFIG_PATH prior to host/build, but I guess
it makes sense to explicitly mention it. Thanks.

Last minute typo there. --build should read x86_64-pc-linux-gnu on both places.
Perhaps we could drop the multilib build/host if a brave soul checks mesa
(src/mesa/main, src/glsl) and confirms that we no longer need them. Otherwise
'make check' will end up failing :\
